Strategic Engineering Simulation

1 Business Initiatives Strateic Enineerin Simulation Today is the era of the virtual world. Your product development roup probably employs some kind of computer testin to vet desin ideas. However, if you take enineerin simulation out of the tactical realm and apply it strateically, you ll discover how it can drive innovation across your oranization. Studies have shown that the cost of chane increases exponentially with each stae of development. ANSYS software not only delivers efficiency but also drives innovation. Modelin and simulation can be used to drive new solutions rather than to merely verify existin ones. Source: Aberdeen Group: The Impact of Strateic Simulation on Product Profitability Global economic pressures are forcin companies to innovate more in a faster time frame and to deliver robust and sustainable solutions from the first product release while keepin costs down. To succeed at these objectives, leadin world-class companies are adoptin enineerin simulation to desin, optimize, manufacture and test new products in the virtual, diital world before committin to production. This virtual approach was used initially for aerospace applications in which failures are not acceptable and physical tests are not always possible. It has quickly spread across other industries, such as automotive, enery, electronics and even healthcare, consumer products and food processin. Business studies confirm that enineerin simulation adoption is leadin to pervasive simulation a world in which no new product desin will be introduced without extensive numerical modelin to optimize and test it. ANSYS is fuelin and drivin this technoloical revolution. Enineerin simulation tools and processes enable enineers worldwide to quickly realize product solutions that address emerin challenes, includin sustainability, safety, enery, medical breakthrouhs and, in short, lobal prosperity and improvement of the human condition. Enineerin Simulation and Simulation Driven Product Development Enineerin simulation involves applyin physics-related software tools to the desin process to create a comprehensive and reliable computer model of any product or process. Usin such a model, you can virtually test operational performance of either existin or potential desins for your products or processes. Without enineerin simulation tools, physical prototypes for each desin candidate must be built and tested throuh physical experimentation. Small chanes to a desin may require manufacturin and testin an entire new prototype, delayin development and increasin costs. Furthermore, a test may yield final results that show a desin to be successful but without any indication or explanation as to how and why it is so. Simulation Driven Product Development takes enineerin simulation to an even hiher level. It involves applyin the principles to the entire product development process, especially in the early staes when it can have the reatest benefit in terms of reduced prototype testin, faster time to market and improved market acceptance of innovative new products. 1

2 Strateic Enineerin Simulation Strateic Business Impact A 2011 market survey by the Aberdeen Group states that current key business drivers are time to market, quality, cost, innovation and sustainability (in order of relevance). Dependin upon the macro-economic situation, the relative importance may chane: For example, cost to market was the primary driver just 18 months ao. Nevertheless, time to market remains a sinificant concern whether the company enjoys a favorable situation or suffers durin difficult times. Top business pressures drivin a better understandin of product behavior Similar investiations conducted amon those involved with simulation clearly state that the direct impact of not usin enineerin simulation is an immediate increase in the number of physical prototypes and the de facto increase in cost and time to market. Other impacts include solutions that lack robustness or are not optimized from the outset. Forward-thinkin product development companies around the lobe many of them the larest in their industries today extensively employ simulation. Usae is spreadin across mid-sized and small companies as simulation becomes more accessible and perceived as an important part of their business processes. At the same time, lare companies that already employ simulation continually increase the pervasive nature of simulation by makin it more systematic, more parametric and better interated into their processes. Leadin impact of NOT usin enineerin simulation As a consequence, no new airplane, car, nuclear or chemical facility, turbine, or enine is currently released without extensive numerical modelin durin both desin and production phases. As simulation becomes more widespread, it is expected that within a decade every major industrial product will benefit from diital investiation durin its desin, manufacturin and testin phases. Real-Life Business Benefits Over the last 10 years, the industrial landscape has completely chaned: Reliable technoloies have fallen short on market demand; consumer expectations have increased in both size and complexity; FORTUNE 500 leaders have wavered due to product interity issues in flaship products; and stron competition is comin from emerin countries. The news media reularly reports on amazin technoloical challenes that pioneerin companies around the world address in the aerospace, automotive, civil enineerin, enery and life science areas, amon others. In parallel, product developers in all corners of the lobe increasinly adopt enineerin simulation. Initially developed for rocket science research a few decades ao but proressively miratin toward industrial desin, this diital prototypin approach has penetrated all major industries and is spreadin step by step into the manufacturin world. 2

3 Strateic Enineerin Simulation It is no surprise to see leadin companies industrial initiatives and enineerin simulation convere, joinin forces to build an innovative future. The results of this successful collaboration are already visible. Thouh enineerin simulation is not a household word, it is used extensively for a hue number of common problems and well-known applications. Not usin this technoloy is considered a competitive disadvantae. Case Studies As more companies use enineerin simulation tools at various product development staes, problems can be desined out before they are manufactured in makin airplanes and automobiles, for example, safer. Vehicle manufacturers constantly work to provide better-lookin, better-performin and more cost-efficient transportation, and virtual analysis helps the industry reach its oals. In the consumer product, businesses that emphasize product development use simulation tools to evaluate alternatives, exclude bad ideas, spot and fix mistakes early on, and optimize desins. And in areas such as construction, industrial equipment, home appliances and plant machinery, Simulation Driven Product Development meets the needs of enineerin customers by providin solutions from concept throuh production.

Simulation revealed micro-flow patterns that can sinificantly impact resistance to motion. Translatin this approach to a virtual swimsuit on a virtual swimmer confirmed the positive impact an advanced swimsuit could have on the swimmer s performance. At the Beijin Olympics, sportin equipment contributed to some amazin performances. Plastic Soda Bottles Every day around the world, we consume 200 million water and soda plastic (PET) bottles more than 10,000 tons of PET discarded into the environment every year. One careful investiation employed enineerin simulation to test different shapes and adjust manufacturin processes, sinificantly reducin bottle weiht without impactin its resistance to shock and droppin. This result has the opportunity to save the planet from 10 percent of current plastic waste, to reduce manufacturin costs, and to consume less raw materials. Life-Savin Electronic Devices Implantable defibrillators have saved countless lives, and the new eneration of these devices will do even more for patients. In the event of a heart attack, a modern defibrillator can simultaneously send a pulse to reset the heart while automatically transmittin a messae to the healthcare team statin that the patient has experienced a major cardiac problem before even he or she knows it. Sinal interference, a common challene for electronic devices, can lead to dramatic consequences. Enineerin simulation 3

Wireless devices today use rechareable batteries so repetitive replacement surery is not needed; but it is crucial that the recharin process desin doesn t induce inconvenience or injury. Consider this case application: If battery rechare results in local heatin, virtual prototypin helps to minimize it, makin the patient safer and more comfortable. Courtesy ACA Enineerin Consultants. Olympic Stadium The Beijin Olympics stadium, the Bird s Nest, is an amazin construction achievement. Durin its anticipated lifetime, it will host exceptional events that draw hue cheerin crowds; it was desined with the expectation that it would survive devastatin winds and a major earthquake. But it was impossible to create prototypes of the intricate structure prior to construction. Similar to other landmark stadiums built over the last few decades, enineerin simulation validated its stability and behavior under a wide rane of circumstances. In another application, desiners used enineerin software to verify parts of the retractable roof over Centre Court at Wimbledon, one of the most famous tennis venues in the world. Resistance to Earthquake Despite their rarity, disasters such as devastatin earthquakes and tsunamis do happen. Commercial buildins as well as important enery and industrial facilities must survive the blow. Simulation can predict a structure s exact behavior in the wake of tremors. If the facility fails virtually, parametric numerical simulation can suest modifications that would ensure its interity. Catastrophic disasters can be virtually modeled via enineerin simulation, ensurin that a product s final desin will successfully survive any real-world event. Project. Cerebral Aneurysm A cerebral aneurysm, the balloonin of an artery in the brain, could be life threatenin if it ruptures. While minimally invasive solutions exist such as coilin and stentin they are not risk free; they should not be considered if the risk of rupture is minimal. Currently, sureons are makin decisions based on aneurysm morpholoy, in which the healthcare team assesses the risk of rupture driven by hemodynamics, or blood flow. Usin a patient s head scan, researchers extract patient-specific aneurysm eometry and model the exact blood flow. The process results in providin the sureon with more information, such as peak pressure, blood flux at the neck, wall shear stress valuable data that can assist in makin the riht treatment decision. This experimental approach is currently bein tested by a number of hospitals. 4

5 Strateic Enineerin Simulation 40 Years of Success Stories: From NASA to Pervasive Simulation for Desin and Production Enineerin simulation emered a number of decades ao out of the need to understand processes in which physical measurement was impossible (nuclear industry>structural analysis) or full-scale preliminary tests were not feasible (aerospace>computational fluid dynamics). Leadin industries (aerospace, automotive, enery, chemicals) and pioneerin companies quickly came to realize the potential benefits of virtual investiations. The first enineerin simulation codes were commercialized in the early 1970s. Rapidly increasin hardware performance quickly enabled a variety of simulation and desin of experiment (DOE) techniques that could be performed. The popularity of numerical simulation in the academic and industrial worlds resulted in an explosion of research to develop reliable and robust models able to accurately predict behavior of ever-more complex structures. This trend initially encompassed only sinle-physics models of advanced fluids, structural dynamics or electromanetics. The market quickly perceived the value of combinin different physics into sinle models, just as reality encompasses multiple domains. Multiprocessor and multi-core computers opened the door to parametric simulation (DOE) and optimization, empowerin desiners to o beyond prediction of complex system behavior. Simulation became a tool used to test future solutions aainst any number of scenarios that could be experienced durin a product s lifecycle a technoloy that could systematically explore a rane of solutions to identify the best one. Enineerin simulation moved far beyond research to development, production and manufacturin. While all industries are not at the same computational maturity, they are all followin the same path of proressively adoptin simulation to model components or entire systems, to challene existin solutions via what-if scenarios, and to virtually optimize a process before deployin it across the company. With the increasin power of hih-performance computin (HPC), desiners are embarkin on includin the probabilistic nature of materials and processes. Specific material properties are never the same, but they vary slihtly around an averae value. The same observations apply to eometry and operatin conditions as well. Althouh these small variations may sound insinificant, combinin them can lead to dramatic consequences. Thus was born the need for desin for six sima (DFSS). Modelin appears to be the only serious option to combine an optimized solution with a probabilistic approach a concept that literature refers to as robust desin optimization (RDO), the new frontier and an important objective. 5

6 Strateic Enineerin Simulation ANSYS Footprint ANSYS has emered as a market leader and a visionary by bein the first, and so far only, company to brin toether the three major physics (fluids, structural and electromanetics) in a sinle environment. Once understood only by pioneerin companies, simulation has been widely adopted as the most effective, efficient and accurate way to predict, challene and optimize new products in the virtual world, reducin time and cost to market without compromisin product interity and sustainability for innovative products. But brinin toether advanced physics into one environment is not enouh, based on feedback from market leaders and enineerin simulation users. Makin advanced multiphysics technoloy easily accessible so that enineers, desiners and manufacturers can systematically take full advantae of it is the next new challene.
